BATHY-500HD Survey Echo Sounder SECTION 1 -INTRODUCTION

1.0 - INTRODUCTION

1.1 GENERAL INFORMATION

The Bathy-500HD Survey Echo Sounder provides a high-contrast thermal chart record complete with alphanumeric annotation

of important parameters such as geographic position, depth, speed of sound and offset for draft/tide. Real-time viewing of all

parameters is provided to the user via front panel liquid-crystal display. Position input can be from either a standard C/A GPS

receiver or differential GPS system. Depth data is available to external devices in digital form, via a versatile interface, whose

format is selectable by the user using the front panel keypad. The user may obtain digital depth data output, in various industry

standard RS-232 formats or NMEA-0183. The ability to accept external annotation input from various PC-based hydrographic

software is standard in the Bathy-500HD.

Unit set-up and parameter changes are accomplished via the keypad. Important parameter values are retained by the unit in

non-volatile memory when power is removed. A real-time internal clock provides time and date stamping of the chart record.

The Bathy-500HD is equally well suited for both applications which involve rapid depth of channel determination by viewing

the chart record and for detailed hydrographic surveys whereby automatic operation and unattended logging of digital depth

data is desired. The use of embedded parallel microprocessor architecture allows for operation of the chart recording function

simultaneously with digital display and data outputs, while further having the real-time capability to implement a proven

weighted bottom detection technique, adaptive bottom tracking gate and other advanced signal processing.

Entirely portable, the Bathy-500HD can be operated on any vessel of opportunity since a wide range of A.C. and D.C. input

voltages can be used. Your Bathy-500HD is capable of operation on various frequencies as selected by the user; See Section

3.3.1 for frequency selection procedure. Space is provided in the rear of the unit to store the various transducer types. Since

scale annotation is printed on the chart along with bottom features, only one type of chart paper is required; The user need not

change paper type when changing measurement units from feet to meters or vice-versa.

1.2 ECHO SOUNDING OVERVIEW

Echo sounding measures water depth by measuring the time interval required for ultrasonic sound waves to travel, at a known

velocity, from a known point (a vessel) to a reflecting surface (water bottom) and return. If the time is measured between the

transmission of a sound wave and the reception of its echo, the depth may be determined by multiplying one-half of this time

interval by the velocity of sound in the water column.

For accurate surveying, sound velocity (more correctly referred to as speed of sound since it is really a scalar value) must be

determined and entered into the echo sounder. Sound speed in water is dependent upon the salinity, temperature and depth. For

instruments that operate in shallow depths, as is the case for the Bathy-500HD, depth is not a major factor effecting sound

speed, so such is not considered in this manual. Complete details regarding the various methods available to the user to

measure or estimate sound speed is included in the chapter which describes unit operation (Section 3.0).

Under optimal desired survey conditions, only a single trace will be shown in the water column; That, of course, representing

the water bottom. Various conditions do however exist which result in other marks between the zero line and obvious water

bottom. Physical conditions such as a rapid temperature gradient (thermocline) or density variation (pycnocline) can form an

acoustically reflective layer between the zero mark and true bottom. Further, dense biological material (plankton) may have the

same effect While the user may,in many cases, easily recognize these layers (as represented on the paper chart), automatic

digital depth tracking, display and output may be effected. In such cases, a blanking feature (manual gate feature on the Bathy-

500HD) is required for robust, reliable unattended surveying.

2.6.2 Data Input

2.6.2.1 GPS Input

Your Bathy-500HD will accept NMEA 0183 input sentences containing GPS postiton in either GGA or GLL format. The unit

auto detects when GGA is present in a sentence and accepts such as its first choice of position. Input position and unit

time/date can be annotated on the chart record. The unit will accept input data in RS-232 input levels as denoted in section

2.6.1

The standard NMEA 0183 data transmission format is as follows; Data is transmitted in serial asynchronous form in

accordance with ANSI standards. The First bit is a start bit and is followed by data bits, least-significant-bit first as illustrated

below. The following parameters are used: Baud rate = 4800/9600/19200/38400/57600, Data bits = 8 (d7 = 0), Parity = None,

Stop bits = One.

2-10

2.6.2.2 External Annotation Input

In lieu of GPS position your Bathy-500HD will accept external annotation from various PC-based hydrographic software; Up

to forty-four characters (Alphanumeric-uppercase) may be printed vertically. Serial input is made to the same hardware pins as

is used for GPS input; See Section 2.6.1.

To start an annotation string, "CONTROL F" then "CONTROL A" is inputted; This is followed by up to forty-four characters,

then "CONTROL D" to end the string. Simply put, the sequence is shown below.

(CNTRL F) (CNTRL A) (ANNOTATION) (CNTRL D)

Should the user not desire vertical annotation but instead desire a vertical fix mark line, only a (CNTRL F) need be sent from

the PC.

2.6.3 Data Outputs

Section 2.6.3 lists the various data output formats available from the Data I/O at the Bathy-500HD. This section provides more

detailed, information for each format (sentence) to allow the user to interface with external peripheral devices Hardware pin-

out connections are listed in section 2.6.1.

2.6.3.1 ODOM dt Format

Your Bathy-500HD emulates the digital depth output of the ODOM Digitrace depth digitizer unit. To receive ODOM dt format

data, the user will connect his external receiving device to the ANNO connection on the rear center plate. The ODOM standard

output data string contains 11 characters as shown below; No parity is used and the sentence has 8 data bits and 1 stop bit.

Byte 1:

An ASCII "F" (hex 46) appears as the first byte in the string whenever the operator depresses the recorder MARK

key. The depth value in the output string reflects the depth at the point which the key is pressed. At all other times the ASCII

"space" (hex 20) appears at this location.

Byte 2 & 3:

Characters 2 and 3 contain the unit identifiers. These are set to "D" and "T" (hex 44, 54).

Carriage Return (*space at all times)

D T 1 * * 2 0 C

R

Depth

(Example 1.20 units)

(00 indicates error)

"F" on MARK (FIX)

(*space at all other times)

"E" on error

(*space at all other times)

Decimal point understood

* Leading zeros are suppressed





2-11

Byte 4:

Position 4 is reserved as an error indicator in the form of an ASCII "E" (hex 45) and coincides with all zeros in the

depth field. An ASCII "space" is present at all other times.

Byte 5:

This location will always contain the ASCII "space".

Byte 6 thru 10

True depth is given in these five positions with the decimal point understood to be fixed between bytes 8 and 9.

Leading zero suppression is applied to the first two digits of depth. For example, for a depth of 8.5 feet, the five digits would

appear as: space/space/8/5/0.

Depth in the output sentence will be corrected for Offset and Speed of Sound. In the event of an error due to loss of bottom

tracking two zeros will appear in the depth field and the "E" character will occur in byte 4.

Byte 11:

A carriage return delimiter (hex )D) is always placed at the end at the string.

2.6.3.2 ODOM et Format

This output emulates the ODOM Echotrac output sentence as shown in the example below.

_E T_ _ _ x x x x

During normal operation the "space" in front of the "E" will be blank; When a Fix Mark is initiated, this space will contain the

character "F". During proper equipment operation, the "space" immediately after the "T" is blank; Should the bottom be lost, an

error condition s indicated by the character "E" being placed in this space.

Output in "FEET" units is denoted as "ET" while output in "METERS" is denoted as "et".

"1234" equals 123.4 feet). If in Metric mode, there would be two places after the decimal, thus "1234" equals 12.34 meters.

Note that zeroes are suppressed.

2.6.3.3 PMC dt Format

The structure for this industry standard output is shown below.

_D T_ _ _ x x x . x _FT (English mode)

_D T_ _ _ x x . x x _MT (Metric mode)

During normal operation the "space" in front of the "D" will be blank; An "E" in this space indicates an error such as lost

bottom while an "F" indicates a Fix Mark.

2.6.3.4 NMEA dbt

Data output will be NMEA 0183 depth below transducer sentence format as shown below.

$ S D D B T , x x x . x , f , x x x . x x, M , x x . x , F

Where x x x . x = feet (f) x x x . x x = meters (M) x x . x = fathoms (F)





2-12

2.6.3.5 NMEA dbs Format

Data Output will be NMEA 0183 depth belowsurface sentence format as shown below.

$ S D D B S , x x x . x , f , x x x . x x , M , x x . x , F

Where x x x . x = feet (f) x x x . x x = meters (M) x x . x = fathoms (F)

2.6.3.6 DESO-25 Format

This data output emulates the output sentence of the Atlas DESO-25.

D A x x x x x . x x Ft * (English mode)

D A x x x x x . x x _m * (Metric mode)

Note that an asterisk is always used as a terminator at the end of the sentence. Also note that in the Metric mode, a blank space

will always appear in front of the "m" character.

2.6.3.7 ODEC dpt Format

This data output string is ODEC’s comma delimited proprietary format containing Time and Position (from a GPS device), true

depth, and depth status. This format is depicted below:

$ S D O D C , h h : m m : s s , a y y . y y . y y y y , o x x . x x . x x x x , f , x x x x . x , u , v

Where h h = UTC Hours m m = UTC Minutes s s = UTC Seconds

a = N / S Latitude y y . y y . y y y y = Latitude Degrees, Minutes, Decimal Minutes

o = W / E Longitude x x . x x . x x x x = Longitude Degrees, Minutes, Decimal Minutes

f = Depth Frequency (A = Low Frequency or Only Frequency, B = High Frequency)

x x x x . x = True Depth u = Units (M = Meters, f = Feet) v = Depth Status (A = Valid, V = Invalid)

2.7 CHART PAPER INSTALLATION

With your Bathy-500HD, two P/N P01200 Chart Paper Roll Kits are supplied. Additional kits are available from SyQwest

Incorporated. Do not use other paper types in your Bathy-500HD. Attempted use of other media will result in improper

contrast shading and potential damage to the thin-film printhead. Do not attempt to substitute paper take up rolls as the roll

furnished with the kit is designed (size and tolerance) to precisely fit the paper shaft. Use of any paper kit other than that type

specified herein will void the thin-film thermal printhead warranty.

Before beginning installation of a new paper roll, perform the following:

1) Remove the empty supply roll liner and full take up roll.

2) Clean debris from both paper shafts (under no circumstances add lubricants to shafts).

3) Place your print head lift arm in the UP position (as shown in the diagram below).

4) Use a dry cloth to clean any debris from the surface of the paper sensor (see below).

(continuing the paper installation process)

5) Install the new paper take up roll onto the take up paper shaft as shown below.

6) Install the new supply roll onto the supply paper shaft and feed the leading edge of the paper over the printhead

roller, under the printhead assembly, across the chart module and down to the return slot and to the take up roll.

7) Use the take up clutch spool to adequate paper (for holding) onto the take up roll and to pull the paper taut across

the chart module face.

8) Return the printhead lift arm to the down (closed) position (shown below).

Insure that the paper is aligned with the platen bottom

3) Hyperterminal: This must be “copied” from the CD to your PC, then create a “shortcut” to the exe file.

2.9 Bathy-500HD Host PC Ethernet Interface

The Bathy-500HD Unit communicates with the Bathy-500HD Windows PC Host Application via a single

Ethernet interface connection. It is very important to setup the Ethernet connection properly within the

Windows configuration to ensure a reliable connection at all times.

The Windows operating system is designed to permit most connections to be “plug and play” so

connecting any hardware device to a Windows PC is simple for the user.

In the case of the Bathy-500HD, the Windows PC is part of a real-time data acquisition system so the

LAN configuration for the Bathy-500HD Ethernet setup needs to be setup as a dedicated TCP/IP

connection for optimum system operation. The sections below detail how to setup the connection

properly, with the correct IP Address, and Sub Net Mask.

Once the Bathy-500HD setup is complete and the network connection has been established, the user must

also evaluate any other network connections that are connected the Bathy-500HD Host PC. The Bathy-

500HD system can work with other LAN connections connected to the PC but due to the real time nature

of the acoustic data acquisition, heavy loading on another LAN connection can cause issues with the

Bathy-500HD sensor to host interface.

2.9.1 Setting a Static IP Address for Network Connection

To set up your computer, follow these steps. Go to: Start Settings Network Connections Right click on the “Local Area Connection” icon and select “Properties” You should see the following, or similar type screen:





2-16

Scroll to and Click on “Internet Protocol” and then on “Properties” You should see the “Internet Protocol (TCP/IP) Properties” window.

You can either set up the interface under the “General” setup or the “Alternate Configuration” tab. If you have 2 or more Network connections available, you may want to use the “General” settings on your selected Network card. Click the “Use the following IP address” radio button and set it up with the IP address shown below (the

same as shown below under “alternate”). If you already use that connection, or you are limited on your network connections, you can select the alternate tab. When selected it will be displayed with “Automatic private IP address” selected.

Click the “Use the following IP address” radio button Enter the IP address information shown below Select “OK” For use with the Bathy-500HDPC, it is required that you use the 192.168.199.113 address.





2-17

If you have only one network connection, and you move the network cable from your standard network connection to the Bathy when collecting data, you may prefer to set up the “alternate configuration” as shown to the left. This will preserve your “main” network settings, and default to these only when plugged into the Bathy.

2.9.2 Setting an Alternate Static IP Address for Network Connection

If you move your computer from being connected from a LAN using DHCP to your Bathy-500HDPC or other equipment that uses a static IP address, you can set your computer up to automatically switch to the “alternate” static IP address. Click on the “Alternate Configuration” Tab and set the IP Adress the same as shown above.

The use of the alternate IP address occurs when the computer cannot find a DHCP server such as when it is connected to your Bathy-500HDPC.

2.10 Data Retrieval from Bathy-500HD

Connect a CAT 5/6 ethernet cable from the User computer to the RJ-45 jack on the rear of the center plate on the Bathy-

500HD Sensor Unit. To retrieve the data from the on-board memory, install, and open the “FileZilla Client” software that was

included on the installation CD. In the Host box in “FileZilla” enter the IP Address 192.168.199.111 as (Shown Below). Click

the “Quickconnect” option.

The connection will show the “Local Site” (your pc) and the “Remote site” the Bathy-500HD. The stored data files will appear

on the (right side panel) “remote site” window of the FileZilla program. Set the “Local site” to the drive or location you wish to

“save” the data files to (using the left side panel). Then “Highlight” the “folder” or “file” you wish to download, right click the

“Highlighted item” and select “Download” this will initiate the transfer of the files to the folder location on your computer.





2-18

2.10.1 Raw Data Conversion to SEGY Data Format

Open the Bathy-500Hd software on the Host Computer. Select “Convert SYQ to

SEGY” located under “tools”.

Open the files that were transferred from the Bathy-500HD to the specified local

drive.

The program will convert the selected file from SYQ format

to industry standard SEGY format. The new SEGY format

files will be stored in the same file directory that the SYQ

files were placed by the user.

At this point, the SEG-Y Header window will pop up, you

may enter any specific information at this time.

During the process,the Bottom Status Bar will display “Converting”.

The Pop up window will show when the conversion has completed.





2-19

2.11 Viewing Digital Playback of Data

After the user has converted the SYQ data to SEGY data, the digital data can be used with the playback function of the Bathy-

500HD software. Open the data file by using the “Open for Playback” option located under “File” on the main toolbar. Select

the desired SEGY data file from the file directory. The user can control the playback function by using the following buttons

located on the toolbar of the Bathy-500HD software.

The user may determine the sound velocity applicable to a specific survey using three methods:

A) Obtaining the measured sound velocity value from an external sound velocimeter.

B) Performing a "BAR-CHECK" using the Bathy-500HD. To accomplish such, a plate (bar) is placed at a known

depth below the transducer face The user then varies the speed of sound value until that exact depth is displayed on the DEPTH

display page (and, of course, the chart). At that point of agreement the entered sound velocity value will be correct for the

specific survey area and time. In effect, the Bathy-500HD contains an integral sound velocimeter.

C) By estimating the sound velocity considering the salinity and temperature of the given survey area and time

APPENDIX A provides a matrix of speed of sound values for various combinations of salinity and temperature.

3.3.8 GATE Key

Depressing the GATE key once allows the user to view whether the gate function is disabled (Off), designated to be automatic

(Auto) or Manual Screen pages denoting the first two settings are shown below.

When the gate function is off, the first acoustic return (bottom or other) will be digitized and displayed as depth. In the

automatic mode, a self-adaptive gate, based upon real-time mathematical modeling will be established. This mode provides the

most robust digital bottom tracking. The user toggles between Off, Auto and Manual screens by pressing the GATE key.

The Manual mode is used when physical or biological conditions cause a "false bottom' in the water column. In such cases, the

user may direct the Bathy-500HD to digitize acoustic returns only below that depth.

Once in the Manual mode, the user may change the false bottom blanking depth via the IMCREMENT and DECREMENT

keys. Depressing ENTER will then accept that value. An example of the Manual mode page is shown below.

BATHY-500HD Survey Echo Sounder SECTION 4 -MAINTENANCE



4-1

4.0 - MAINTENANCE

4.1 GENERAL

Your Bathy-500HD consists of individual functional modules as to provide for highest probability of field repair thus reducing

survey downtime. No internal adjustments or calibration of the functional modules are required thus the recorder is serviceable

by users without extensive knowledge of electronics or special test equipment. Section 4.6 provides a listing of all functional

modules, hardware items, and cables which may be needed should your recorder ever fail.

4.2 FUNCTIONAL OVERVIEW

Printed circuit board assemblies (functional modules), along with the thermal printhead assembly and step motor, comprise the

key sections of your Bathy-500HD recorder unit. A general technical overview of each printed circuit board containing active

electronics follows:

4.2.1 Power Supply

The Bathy-500HD power supply module functions to convert ac line voltage or low-voltage dc, power to regulated 24 volts

D.C. to service all other functional modules. Other voltages (i.e. +5v D.C.) required by other modules is generated locally on

each such assembly. The B.I.T.E. indicator (green LED) located on the power supply PCB verifies proper operation or this

assembly, thus 24 volts D.C. is available to other modules.

4.2.2 Key/Display PCB

The key/display printed circuit board serves to interface the CPU PCB to the liquid-crystal display and keypad. Keystrokes are

converted to digital messages to be implemented by the CPU PCB, which collates bi-directional data from the other functional

modules and communicates with the user thru the front panel display.

4.3 DIAGNOSTIC CHART

(SEE APPENDIX B FOR SELF-TEST FEATURES)

SYMPTOM CHECK & ACTION

Unit does not power-up 1) Check fuses; replace if defective.

2) Use Local On /Off switch on power supply PCB to attempt to power-up unit; If

depressing this switch turns unit on, replace the key/display PCB; If not, replace the power

supply PCB.

LCD functions; Chart does not 1) If the chart moves (but does not print) replace the printhead.

2) No chart movement Check to insure paper is covering paper sensor (without wrinkles);

If so, and still no movement, go to step 3.

3) If the chart does not move, replace the print/drive PCB paper sensor PCB or step motor

as applicable

No display or record of depth 1) Check transducer connections

(other functions are normal)

No GPS data or depth data output 1) Verify proper operation of external devices.





4-3

4.4 CLEANING

4.4.1 Printhead Care

Your Bathy-500HD utilizes a long-life thin-film thermal printhead. While robust, care must be taken as to not allow sand and

other such matter to come in contact with the printhead face. Should the interior of the case become contaminated with any

such matter, stop operation at once; Raise the printhead assembly by using the lift arm, remove the paper and use dry air to

remove all such particles from around the printhead and chart module paper travel surface. Never clean the printhead surface

with anything except a cotton swab, which has been moistened with Isopropyl alcohol. DO NOT USE ANY OTHER

SOLVENT.

4.4.2 Printhead Roller

It is important to maintain a clean printhead roller to prevent slippage during printing. Before cleaning the printhead roller,

always raise the printhead using the lift arm. Use a cotton swab to clean the roller. If a solvent is needed, use only isopropyl

alcohol. Do not use any other solvent; the roller is synthetic rubber and will be damaged.

BATHY-500HD Survey Echo Sounder APPENDIX B –SELF TEST FEATURE



APPENDIX B 1

APPENDIX B. - SELF TEST FEATURE

Your Bathy-500HD contains an automatic self-test, which is initiated each time the unit is turned on. The display shown below

generally indicates a properly functioning Bathy-500HD. Upon normal self-test (no errors found), this display screen will

automatically clear itself.

As shown above, the designation "ok" next to the designation indicates normal (proper) functioning. Should the self-test

routine detect an error, the self-test will halt after the last operation is tested; The procedure will not continue until the first

problem is corrected. Then upon power-up again, the procedure will continue. For example, the display shown below indicates

proper operation of the CPU and Print/Drive but a failure with the T/R. The Data I/O cannot thus be tested until the T/R is

repaired.
